DETAILED DESCRIPTION

The disclosure disclosed herein is a lighting system and sensor array for facilitating the growth of plants, wherein the lighting system provides a desired spectrum and intensity of light. The disclosure disclosed herein can be understood with reference to U.S. Pat. Nos. 8,297,782, 8,668,350, 9,310,027, and 9,310,049, the contents of all of which are incorporated herein by reference in their entirety. The disclosure disclosed herein can be understood with reference to the above-identified U.S. patent application Ser. Nos. 15/004,320, 15/406,458, and U.S. Provisional Application No. 62/303,374. The position indications discussed herein can be of many different types of indications, such as an electrical signal. The electrical signal of the position indications can be of many different types of electrical signals, such as a digital and/or analog position signal.

Many greenhouses in northern climates use supplemental light to increase growth of crops in low light seasons and environments. The duration and integrated quantity of light, in the form of Photosynthetically Active Radiation, a plant receives over a day impacts growth, quality, and yield for greenhouse crops. The sum of photons in a unit area over a day, known as Daily Light Integral or DLI, is used by growers to plan crop growth schedules. Although DLI is well correlated to growth, this metric does not address duration of light during a day, known as photoperiod.

Work by Jiao et al. (1989) on roses, and Logendra and James (1992) on tomatoes have shown plants grown under longer photoperiods with a similar DLI produce more overall growth and accumulate a higher dry mass when compared to shorter photoperiods. To determine the optimal photoperiod for currently relevant day-neutral horticultural crops we grew plants under the same DLI with different photoperiods to determine an optimal photoperiod for production. Tomatoes and lettuce were grown in a growth chamber under a DLI of 12 mols/day with 12-Hour, 16-Hour, 20-Hour, and 24-Hour photoperiods to test effects on growth, development, and mass. Tomatoes grown for three weeks under a longer photoperiod of 20-Hours averaged a 45%-67% increase in dry mass and grew 31% to 44% taller in height in comparison to plants with a 12-hour photoperiod. Lettuce showed similar results, as the 20-Hour treatment produced plants with 38% more wet mass and 36% more dry mass in comparison to the 12-Hour treatment. Under a 24-Hour photoperiod, tomatoes developed intumescence and lettuce had significantly less wet and dry mass, suggesting the importance of a dark period. These finding will be tested in a full production greenhouse environment, to explore the benefits of achieving both a target DLI and target photoperiod on marketable yield, by adjusting supplemental light intensity in regards to the light provided by the sun to create an optimal lighting environment.

The light sensor 127 is integrated with the housing 125 and sensor 127 can be externally and/or internally positioned with the housing 125. The housing 125 can be configured to protected and/or house grow light 120 and corresponding LED arrays 128 and 129.

FIG. 1c is close-up view of the LED 128 a of the LED array 128. The LEDs 128 a can be of many different types.

It should be noted that an LED emits light in response to being activated, and an LED does not emit light in response to being deactivated. An LED is activated in response to driving a current through it to a current level above a threshold current level. Further, an LED is deactivated in response to driving a current through it to a current level below the threshold current level. In this embodiment, the LEDs 128 a and 129 a are activated and deactivated in response to receiving a signal from an LED controller.

It should be noted that the light emitted by the LED arrays 128 and 129 are mixed together. In this way, the LED arrays 128 and 129 provide color mixing. The light of the LED arrays 128 and 129 can be mixed together to provide a desired wavelength spectrum of light and/or a desired intensity of light, as will be discussed in more detail below.

It should also be noted that the intensity of the light emitted by a single LED typically has a Gaussian wavelength distribution. However, some LEDs, such as those which provide white light, have intensities that have non-Gaussian wavelength distributions. An LED which provides white light and has an intensity having a non-Gaussian wavelength distribution.

The wavelength spectrum of the light emitted by an LED can be chosen in response to choosing the band gap energy of the semiconductor material of the LED. The band gap energy of the semiconductor material of the LED is typically chosen by choosing the semiconductor material composition. The semiconductor material composition can be chosen during growth. It should be noted that the wavelength distribution of the light emitted by an LED can be chosen in response to choosing the semiconductor material composition. The semiconductor materials included with different types of LEDs can be of many different types, several of which will be discussed in more detail presently.

LEDs which emit IR light can include many different types of semiconductor materials, such as gallium arsenide and aluminum gallium arsenide.

Hence, the LEDs of LED array 102 can provide light having many different wavelength values, such as those mentioned above. The LEDs of LED array 102 can be provided by many different manufacturers, such as Cree, Inc. of Durham, N.C. and Nichia Corporation of Tokyo, Japan. In this particular embodiment, however, the LEDs of LED array 102 are provided by Philips Lumileds Lighting Company and are referred to as Luxeon-III light emitting diodes.

The LEDs of the LED arrays 128 and 129 include two or more different types of LEDs, which are capable of emitting different wavelength spectrums of light. LEDs of the same type emit the same wavelength spectrums of light, and LEDs of different types emit different wavelength spectrum of light. A wavelength spectrum of light is the intensity of light emitted by the LED versus the wavelength of the light, and corresponds to a color of the light. The wavelengths spectrum of light can be determined in many different ways, such as with a spectrometer. Examples of wavelength spectrums of light are discussed in more detail below.

It should be noted that the conventions for the wavelengths of different colors of light vary widely. However, the wavelengths of light discussed herein will have the following ranges for ease of discussion:

-   -   Ultraviolet light (UV): 40 nm to 380 nm;     -   Violet light: 380 nm to 450 nm;     -   Blue light: 450 nm to 495 nm;     -   Green light 495 nm to 570 nm;     -   Yellow light: 570 nm to 590 nm;     -   Orange light: 590 nm to 620 nm;     -   Red light: 620 nm to 750 nm; and     -   Infrared light (IR): 750 nm to 2500 nm,

wherein the wavelengths above are in nanometers (nm).

It should also be noted that the grow lights of the grow light array 100 can be the same types of grow lights, or the grow light array 100 can include different types of grow lights. For example, the grow lights 120 a and 121 a can correspond to the grow lights 120 and 124, respectively.

The positions of the grow lights of the grow light array 100 can correspond to many different positions. In one embodiment, the grow light array 100 is positioned proximate to one or more plants. The grow lights of the grow light array 100 are spaced apart from each other so that the plant(s) receive a desired spectrum and/or intensity of light, as will be discussed in more detail below.

FIG. 4 is a graph 150 of light spectrums 150 a and 150 b, wherein the graph 150 corresponds to the intensity of light verses the wavelength of the light. The graph 150 a corresponds to more intense light, and the graph 150 b corresponds to less intense light. Hence, the graph 150 a corresponds to light with a greater intensity than the light of the graph 150 b. Further, the graph 150 b corresponds to light with a smaller intensity than the light of the graph 150 a. The light of graphs 150 a and 150 b can be of many different types.
